"Fast" is a song co-written and recorded by American country music artist Luke Bryan. It was released in November 2016 as the sixth and final single from his 2015 album Kill the Lights.
The song is about "contemplating the speed of life" and noting how events in life move "fast", especially as one ages. Bryan told Billboard that the song came about during a writing session with Luke Laird and Rodney Clawson. They were having little success with one song idea until Laird provided the word "fast", and the writers came up with the song's first two lines. The verses take place while the male narrator is a teenager and aspiring for things that are "fast", while the chorus shifts to the narrator's adulthood, where he observes that he is frustrated by his inability to "slow down the passage of time" as stated in the lyric "60 seconds now feels more like 30", a lyric provided by Bryan. The song's recording session includes drums from Greg Morrow overlaid by programmed drum sounds provided by Jody Stevens, along with electric piano from Mike Rojas and "glassy whole notes" from session guitarist J.T. Corenflos.
